nandflash读写问题

自己做了一块板子，参考的是官方的原理图，把nand512r3r换成了s30ms01gp25tfw50，参数变成了有1024block，每块64page，每page2048bytes，然后我将mcsdk里的例程nand_write_evmc6678l里的相关参数做了更改，再向里面烧写数据，主函数里调用了两个flash_nand,第一个调用时没有报错，到了第二次调用时在执行flash_nand里的函数时到了块检测那一步就报错了，请各位大侠不吝赐教

flash_nand程序如下

flash_nand

PLATFORM_DEVICE_info *p_device
)
{
uint32_t wPos, wLen;
uint32_t block, start_block;
uint8_t *scrach_block;

}
}

/* Program the NAND */
for (block = start_block, wPos = 0; wPos < nandWriterInfo.writeBytes; block++, wPos += nandWriterInfo.blockSizeBytes)
{
while(checkBadBlockMark(p_device, block))
{
printf ("Bad block # %d detected, skipping block … \n", block);                 这里报错
if (++block == p_device->block_count)
{
printf ("Flash failed: End of device reached\n");
if (swap_byte) free (scrach_block);
return (FALSE);
}
}

printf ("Flashing block %d (%d bytes of %d)\n", block, wPos, nandWriterInfo.writeBytes);

platform_device_erase_block(p_device->handle, block);

wLen = nandWriterInfo.blockSizeBytes;
if (nandWriterInfo.writeBytes – wPos < nandWriterInfo.blockSizeBytes)
{
wLen = nandWriterInfo.writeBytes – wPos;
}

if (swap_byte)
{
formBlock((uint32_t *)(&nandWriterInfo.writeData[wPos]), nandWriterInfo.blockSizeBytes, scrach_block);
}
else
{
scrach_block = &nandWriterInfo.writeData[wPos];
}
if (platform_device_write(p_device->handle, block*nandWriterInfo.blockSizeBytes, scrach_block, wLen) != Platform_EOK)
{
printf ("platform_device_write block # %d failed!\n", block);
print_platform_errno();
if (swap_byte) free (scrach_block);
return (FALSE);

}

如果你用flash参数不一样，可以改一下源码，然后重新编译一下再使用。

mcsdk中自带例程中的的读写nandflash的例程，想问一下nandwriter_evmc6678l，想问一下这个工程里调用的库文件里是不是把nandflash的相关参数已经设定好了，如果换用其他的nandflash则无法使用这个库文件
